Wow, what an amazing looking application. I've been waiting for something like this!

I've just started using it myself. The one thing I'd like to see added ASAP would be the ability to scroll up and down your twitter timeline with the arrow keys on the keypad. I almost exclusively use the arrows for navigation around webpages as it's easier to do one handed than using the touchscreen, and am sorely missing this feature in this app.

Other than that, it really does look amazing so far, keep up the good work!
